T0 all?, whom it may concern:

Be it known that I, WILLIAM R. ROTH- WELL, a citizen of the UnitedStates, residing at West Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Fountain-Pens, of which the following is a specification.

My invention has relation to fountain-pens of the type wherein theink-reservoir is formed of a flexible or elastic sack and inclosedwithin a barrel of hard material and the feed of ink to the pen or tothe sack is accomplished by compressing or dilating said sack.

The principal obj ect of my invention is to provide in a fountain-pen abarrel of rigid material, a flexible or elastic sack inclosed in saidbarrel and constituting the ink-reservoir, means connected with saidsack and arranged to slide about said barrel, whereby the sack may becollapsed or dilated, and a closure for the lower end of said sackarranged to partially surround the pen and the feed therefor.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, in which- Figure l is a verticalsectional view of a fountain-pen embodying main features of myinvention. Fig. 2 is a cross-sectional view taken on the line 2 2 ofFig. l, and Fig. 3 is a perspective view of the pen and feed-shieldforming flexible sack and rigid barrel.

Referring to the drawings, a is the barrel, formed, preferably, of hardrubber and inclosing a sack d, of flexible or elastic material,

the closure for the lower end of the This saclrdis preferably closed vatits upper end and united to the interior of a cap a', arranged to slidearound or about the barrel a to thereby dilate or collapse the sackcl.Inthe lower open end of the sack d and of the barrel a is arranged ahood c, having a tubular extension c The body of the hood @forms aclosure for the sack, and the extension c surrounds a feeding-finger a3and the pen proper, a4. The coiled body a2 of the feeding mechanism isinclosed in the body of the hood c, and the body of the hood c serves toclamp or hold the open end constituting the ink-reservior.

of the sack d to the interior wall of the barrel a.

In the operation'of the pen a slight movement of the cap a serves toforce the ink in the reservoir to the feed a2 a3 by compressing theflexible sack (l. A pull upward upon the cap dilates the sack d andserves to suck ink upward into the sack through the tubular extension cof the hood c.

Having thus described the nature and object of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

In a fountain-pen, a rigid barrel, a flexible sack inclosed by saidbarrel, means secured to the sack and arranged to slide about the barrelto compress or dilate said sack, anda closure for the lower portion ofthe sack arranged to surround the pen proper and feed therefor.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
